Improvement in cotton-gins



UNITED STATES PATENT Orino@C ENOOH OSGOOD, BOSTON, MASSACHUSETTS.

IMPROVEMENT IN COTTON-(BINS.

Specification forming part of Letters Patent No. '5.84 S, dated October 18, 1859.

To all whom, it 71mg concern.'

Be it known that I, ENooH OsGooD, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Cotton-Gin, which is also applicable to burring wool; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specilication, in which-- Figure 1 is a side elevation of my invention; Fig. 2, a transverse vertical section of same, taken in the line .t x of Fig. l. Fig. 3 is a longitudinal vertical and central section of same.

Similar letters of reference in each of the several figures indicate corresponding parts.

This invention relates to an improvement in the roller-gin, whereby the advantage attending the use of this kind of gin is obtained-to vwit, the separating of the seed from the staple without injuring the latter-and at the same time a great speed obtained, so that the work will be done very expeditiously as well as in a perfect manner.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a rectangular box, in which two rollers, B B, are placed transversely-one over the other-in the saine plane, as shown in Fig. "3; and O O are two angular plates,which are also placed in the box A, their inner surfaces being in line with the center of the space between the rollers B B'. The plates C C, it will be seen by referring to Fig. 3, are of rectangular form. The lower plate O is secured permanently in the box 5 but the upper one C, by means of set-screws a a at each end of the box A, may be adjusted nearer to or farther from the lower plate, the plates being nearer each other at the bite or front corner. This will be fully understood by referring to Figs. l and 3.

Around each roller B and its adjoining plate G an endless band, D, passes. These bands are both shown in Fig. 8, and it will be seen by referring to said ligure that the plates O O cause the bands to work in two parallel or nearly parallel positions, b b, at a point in line with thelcenter of the spa-ce between the rollers. The bands D l) may be of leather,

and the rollers B B of wood or metal. The

lower roller B is driven by power applied to it through the medium of gearing b c, the latter being a pinion on one end of a shaft, E,

which passes transversely through the box A, and has a toothed wheel, F, on its opposite end. Into the wheel F apinion, G, gears, said pinion being on one end of a shaft, H, which passes transversely through the box A, and has a wheel, I, on its opposite end.

To the pinion G and wheel l, which are of equal diameter, curved arms or bars J are attached-one to each. These arms Orbars are attached eccentrica-Hy to the pinion and wheel, as shown in Fig. l. and bythe dotted lines in Fig. 3. The front end of each arm or bar J is expanded, and has two curved slots, d d, made through it. These slots are of precisely the same shape, but have reversed positions, as shown clearly in Fig. l.

In the upper slot d of each arm or bar J a pin, e, is fitted. These pins are each attached to barsf-one at each side of the box A-said bars being secured at one end to the box by pins or bolts g, and by set-screws 7i at the opposite end, said set-screws passing through curved slots in the bars to admit of the adjustment of the bars and consequently the pins e.

In the lower curved slots d of each arm or bar J pins t t-one in each. These pins are attached to opposite sides of a clearer, K, which is placed in the box A directly in front' of the rollers B B, in close proximity to the vertical run of the belts. This clearer is formed by having two serrated plates, jj, tted in a frame, k, the toothed or serrated edges being opposite each other, as shown in Fig. 2, which are preferably to come close enough together that the seeds of the substance being operated upon shall not escape by them or l through or between their serrated edges.

L is a feed-board, fitted in the box A in an inclined position, and having rods Z at itslower end, the rods forming a screen to allow the cotton-seed or wool-burrs to pass through.

M is a spring, which is attached to one of the pins i of the clearer K. This spring is attached to one side of the box A. one or more springs, M, may be attached on each side of the box A, and to each pin i of the clearer. The upper roller, B, may be adjusted higher or lower in the box A by setscrews at.

If desired,

The operation is as follows: The rollers B B rotate, as indicated by the arrows in Fig. 3, and the cotton on the feed-board Lpasses down between the serrated plates j j ofthe clearer and is caught between the portions b Z) of the bands D D at the corners of the plates C C,

said bands drawing the iiber between themselves, while the clearer K ripples the seed from the staple as thelatter is drawn between them. The clearer K is operated by the arms or bars J, which are actuated by the pinion G and wheel I, the curved slots` d d, as the bars J move, giving the clearer four vibrations to one revolution of the pinion and wheel G I, and a rapid movement is given the clearer with but a very slight loss of power by friction. The springs M serve to equalize the movement of the clearer, act-ing similarly to a iiy-wheel.

It will be seen from the above description that by having the bands D pass around the plates C C and the portions b b of the bands D form the bite to seize the staple, the

- seed will, with certainty, be stripped from the staple, as they cannot be drawn between the portions b b ot' the bands, and the portions b b of the bands will have a firm hold on the staple, (the pressure being graduated by the screws a,) and still cannot break or out it.

The clearer, in consequence of its quick movement, acts in a very eficient manner in rippling the seed from the staple.

The length of stroke or movement of the clearer may be regulated, as desired, by attaching the arms or bars nearer to or farther from the centers of the pinion 'and wheel G I, and adjusting the pins c accordingly.

I do not claim the employment or use of the clearer K when considered separately, for clearers are common to various forms of gins, but

I do claim as my invention and desire to secure by Letters Patentl. The rollers B B. plates CI C, and bands D, arranged substantially as and for the purpose set forth.

2. The combination and arrangement, in a cotton-gin or wool-burring machine, of the clearer K, rollers B B, angular plates C C, bands D, slotted arms or bars J J d d, pinionv G, and wheel I, in the manner and forthepurpose herein described.
